Task Tree — Organize anything as a tree Task Tree is a simple, powerful task manager built around tree‑structured tasks. Break any goal into projects, tasks, and subtasks — to any depth — and watch progress roll up automatically from the smallest detail to the big picture. Planning a trip, shipping a product, or just keeping a to‑do list? Task Tree keeps everything in a clear hierarchy that's easy to navigate. WHY TASK TREE • Think in trees — Nest tasks as deeply as you need. Big goals become projects; projects break down into tasks and subtasks. • Automatic progress — Check off the leaves and every parent task and project updates its progress for you. • See the whole picture — The Projects screen shows each project's progress, completion count, and due status at a glance. FEATURES • Unlimited subtask depth • Projects with live progress bars and due‑date tracking • Inline due dates with a built‑in calendar • Move a task (and its subtasks) anywhere — or promote it to its own project • Duplicate a task and its entire subtree • Drill‑down and full hierarchy views • iCloud backup & restore — keep your tree safe • Noteholic integration — send a tree to Noteholic, or import a note as a project (indentation becomes your hierarchy) Simple enough for a grocery list, structured enough for a big project. Plant your first tree today.
